WASHINGTON (AP) — Call it spring's fever. Federal records show the U.S. just
finished its hottest spring on record.

March, April and May in the Lower 48 states beat the oldest spring
temperature record by a full 2 degrees. The three months averaged 57.1
degrees, more than 5 degrees above average. That's the most above normal for
any U.S. season on record. Meteorologists define those three months as
spring.

The National Oceanic and Atmospheric Administration also reported Thursday
that it was the second warmest May since records began in 1895. May averaged
64.3 degrees, just behind 1934.

The first five months of 2012 were the hottest start to a year in U.S.
weather record history. The 12-month period starting last June is also the
hottest on record.
